Guess grey sweat pants / joggers

NWOT, only tried on once. I bought these for my boyfriend for Christmas but didn't realise they were joggers (skinnier fit on calves) and he hates them. It's too late for me to return them, so here we are! They are amazingly soft and comfy, I tried them on but I'm a Women's XS/S and these are a Men's S so the waistband is a little too big on me. Make an offer!
